Question: Calculate and plot the external Rmin and Nmin against % product purity for the separation by distillation of an equimolar bubble-point liquid feed of isobutane/n-butane

Calculate and plot the external Rmin and Nmin against % product purity for the separation by distillation of an equimolar bubble-point liquid feed of isobutane/n-butane at 100 psia. The distillate is to have the same iC₄ purity as the bottoms is to have nC₄ purity. Consider purities from 90% to 99.99%. Discuss the results.
